A hydrogen bond forms by the electrostatic interaction of opposite charges in two molecules. If
1 answer:
The force between the molecules involved in the bond is 6. 426 *10^-11 Newton
<h3>How to determine the force</h3>
Using the formula:
F = K[q1 x q2]/D^2
where K is coulombs constant =9 *10 ^9 Nm^2/C^2.
q1 and q2 = charges = 1.60x10 -20C
d = distance between the charges = 2x10 -10 m
Substitute the values into the formula
F =
F =
F =
F = Newton
Thus, the force between the molecules involved in the bond is 6. 426 *10^-11 Newton

Answer:
The volume will not contract to one fourth of the original.
Explanation:
Applying Charles's Law as:
Given ,
V₁ = ?
V₂ = 2 L
T₁ = 5 °C
T₂ = 20 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (5 + 273.15) K = 278.15 K
T₂ = (20 + 273.15) K = 293.15 K
Using Charles law as:
Thus, the volume will not contract to one fourth of the original. (1/4 of 2 L is 0.5 L).
